TeraHertz band communications have been proposed as a notable candidate for the deployment of high data rate networks in 6G and beyond scenarios. While research activity on TeraHertz mostly focused so far on channel measurements and modeling, recently Multi User Interference (MUI) in TeraHertz networks received an increasing attention, as MAC and network algorithms and protocols for TeraHertz networks are being designed.
Existing Impulse Radio TeraHertz MUI models mostly rely on stochastic geometry to determine the MUI power as a function of the positions of the devices generated according to a point process, but either rely on simplified propagation models, or fail to take into account the impact of receiver structure, pulse waveform and modulation options.
The goal of this project is to define an innovative MUI model that takes into account the specific propagation characteristics of the TeraHertz channel, as well as the configuration of the transmitter and receiver. The definition of the model will move from the existing research on MUI for Impulse Radio Ultra Wide Band (IR-UWB) networks in the 3-10 GHz band, leveraging the common characteristics of MUI due to the impulsive nature of the signals shared by IR-THz and IR-UWB, and extend and complement such research so to account for waveforms and propagation characteristics typical of TeraHertz communications.
The model will be evaluated by comparing its predicted MUI contribution at the output of the receiver with the results of system level simulations carried out within a THz communications software package appositely developed within the project as a Matlab app. The package will be equipped with a GUI for maximum usability and released under an open source license to the research community; it will constitute thus by itself a valuable outcome of the project.
